Metal version, flat, with metal front ring, matt, 30 mm

One command point
comprises:

An actuator or indicator in front of the control panel

A holder for securing behind the control panel

Up to six contact modules and/or one LED module (mounted
onto the holder), single-pole contacts can be stacked

A comprehensive range of accessories for inscription/marking

Application

Environmental conditions

The pushbuttons and indicator lights are climate-proof (KTW
24) and suitable for standard industrial applications and operation in
marine applications.

"Intrinsic safety" type of protection EEx i according to ATEX directive
94/9/EC

The pushbuttons and indicator lights can also be used in
hazardous areas. Special versions of the 3SU1400 contact modules und
3SU1401 LED modules (only with screw terminals).

Safety EMERGENCY-STOP according to ISO 13850

For controls according to IEC 60204-1 or EN 60204-1, the
SIRIUS ACT mushroom pushbuttons are suitable for use as safety
EMERGENCY-STOP pushbuttons.

Safety circuits

IEC 60947-5-1 and EN 60947-5-1 require positive opening, i.e.
for the purpose of personal safety, the assured opening of NC contacts
is expressly stipulated for the electrical equipment of machines in all
safety circuits and marked according to IEC 60947-5-1 with the symbol
(->).

Category 4 according to EN ISO 13849-1 can be attained with the
EMERGENCY-STOP mushroom pushbuttons if the corresponding fail-safe
evaluation units are selected and correctly installed, e.g. the 3SK11
safety relays, the 3RK3 Modular Safety System (see Catalog IC 10,
Chapter 11, "Safety Technology") or matching units from the ASIsafe,
SIMATIC or SINUMERIK product ranges.

AS-Interface

The SIRIUS ACT command and signaling devices can be connected
to the AS-Interface communication system quickly and safely.

The following solutions are available:

AS-Interface module

AS-Interface module in safety-related version for
EMERGENCY-STOP mushroom pushbutton

Ready-fitted AS-Interface enclosures with 1 to 6 command
points

IO-Link

The SIRIUS ACT command and signaling devices can be connected
to IO-Link quickly and safely. The connection is made via a special
IO-Link-module.
